Durable 21-in. XHT mower blade with superior hardness for long-lasting sharpness.
Sunbelt B1MA2417 21-in. XHT Mower Blade for 21-in. Decks is designed specifically for mower decks with a 21-inch cut, making it an ideal replacement blade for MTD 21-inch walk-behind mowers. Measuring 21 inches long by 2-1/4 inches wide with a 59/64" by 11/16" center hole, this medium lift, notched blade delivers reliable cutting performance. Sunbelt's XHT (Xtreme Hardness & Toughness) blades are crafted from a unique patented Marbain® heat-treated steel that has been independently tested to provide superior hardness and resistance to bending and impact damage. This advanced steel technology ensures the cutting edge remains sharper for longer, making XHT blades approximately 25% to 40% harder than standard lawnmower blades. The blade maintains tight tolerances, offering performance comparable to original equipment blades from various brands. It is equivalent to MTD, Cub Cadet, White 742-0741 and 942-0741; Oregon 98-049; Rotary 6423; and Stens 335-214, providing versatility and quality for your lawn care needs. Model Number: B1MA2417
